Problems solved by technology

[0003] Although the existing technologies take into account the energy consumption economy brought by the aerodynamics during the driving process of the platoon vehicles, and distribute the energy saving fairly, the distribution method is realized by discriminating and changing the position of the leading vehicle. It is more difficult to implement in queue driving in road traffic

Embodiment 1

[0034] refer to Figure 1 ~ Figure 2 , which is the first embodiment of the present invention, this embodiment provides a method for driving management of platoon vehicles based on aerodynamic optimization, including:

[0035] S1: The vehicle speed sensor is used to collect the driving speed v of the individual vehicles in line.

[0036] When the bicycle is driving on the road, the speed information of the vehicles in the queue is collected according to the position information of the vehicles in the queue and the vehicle speed sensor.

[0037] S2: According to the finite element simulation technology of the cloud platform, calculate the air resistance C and vehicle x encountered by a single vehicle in the platoon vehicle i Air resistance C i .

[0038]The current air resistance C of the vehicle is calculated through the cloud-based finite element simulation technology. At this time, other vehicles start to merge into the driving track of the single vehicle, forming a vehic...

Embodiment 2

[0059] In order to verify the technical effect adopted in this method, this method is based on MATLAB software simulation calculation, uses finite volume method to conduct finite element analysis and simulation of vehicle flow field, and chooses Cartesian grid as the grid strategy of the simulation example.

[0060] In the establishment of the simulation model, CATIA software is used to establish calculation models under various working conditions, including the calculation area. The selected calculation area is a cuboid: the distance between the entrance of the calculation domain and the front part of the front vehicle is twice the length of the vehicle. The exit to the tail of the rear vehicle is 6 times the vehicle length, the side to the outside of the two vehicles is 3 times the vehicle width, and the top to the roof is 4 times the vehicle height, and the surface of the vehicle body is the inner surface of the calculation area; In the simulation calculation of turbulence i...

Abstract

The invention discloses a driving management method for platoon vehicles based on aerodynamic optimization, comprising: collecting the driving speed of a single vehicle in platoon through a vehicle speed sensor; The air resistance C and the vehicle x i Air resistance C i , and transmit the data to the remote tolling calculation platform for vehicles in the queue; when the charging system determines that the fee is deducted, the vehicle in the vehicle in the queue needs to pay a certain fee to compensate other vehicles in the vehicle in the queue; when the charging system determines that it is compensation, The car in the queue will receive an amount of money to compensate for the driving consumption during the queue. The invention can fairly distribute the fuel saving of each vehicle in the queue, and ensure the benefit compensation of individual vehicles while ensuring the fuel economy of the vehicles in the entire queue; it has better management scope and flexibility.

Description

technical field [0001] The invention relates to the technical field of vehicle aerodynamics, in particular to a driving management method for platoon vehicles based on aerodynamic optimization. Background technique [0002] With the development of vehicle technology and road infrastructure in our country, in daily traffic behavior, especially when driving for a long distance on the expressway, it is inevitable to form a state of queuing vehicles. When vehicles are traveling in a platoon, the resistance value decreases with the shortening of the inter-vehicle distance. Under a fixed vehicle spacing, as the number of vehicles in the platoon increases, the average air resistance coefficient of the platoon vehicles can be reduced by 20%-30%, and the vehicle with the lowest resistance is roughly in the center of the platoon. Changes in the air resistance and aerodynamic characteristics of the platoon vehicles bring about improvements in the fuel economy of the platoon vehicles. ...
